(54)	Automatic analyzer and the analyzing method using the same

(57) An automatic analyzer which assures uniformity in mixing effects regardless of sample quantity and test item and thus produces analysis results with high repeatability. The analyzer includes a device for adding a conditioning liquid into a reaction chamber so that the quantity of liquid in the reaction chamber becomes a predetermined quantity at latest just before mixing. The conditioning liquidmaybe adiluent orphysiological saline as used for dilution of a sample or any other special liquid that adjusts the properties such as viscosity, surface tension, etc. of liquid to be mixed.
